a LE a L A I x f amen. .ionnslor s'r. .iosnrngmissonaii' usefulImprovements in fiesilientt liresfof which the following is Thisinvention relates tti res lient tires, having for its primary ob ecttoprovide a tire of'simple and improved constructidii pable of beingreadily applied. to or" re moved from a vehicle rim, and which isconstructed of such material and in such manner as to eliminate theinconvenience incident to the use of penumatic tires.

A further object of the invention. is to provide a tire of the charactermentioned which is formed of a coil spring and arranged in such manneras to be applied snugly to a vehicle rim, and which has its convolutionsso arranged that a number of the convolutions will contact the ground atthe same time, whereby danger of breakage or derangement of the variousconvolutions is obviated.

. A still further object of the invention is to provide a tire of thecharacter mentioned which will possess the desired and requisiteelasticity, and which is equipped with improved means for preventing thetire slipping upon the demountable rim which sup ports the same.

Vith these objects in view, together with others Which will appear asthe description proceeds, the invention resides in the novel formation,combination, and arrangementof parts, all as will be described morefully hereinafter, illustrated in the drawings, and particularly pointedout in the claim.

In the drawings Figure 1 is a fragmentary view, parts broken away, of atire constructed in accordance with the invention, showing the manner inwhich the tire is applied to a wheel rim,

Fig. 2 is an enlarged transverse sectional View through the wheel rimand the im proved tire, and

Fig. 3 is a fragmentary longitudinal view taken through a part of thetire and a demountable rim and illustrating the manner in which theseelements are assembled.

In the drawings, 4 indicates a felly, 5 the spokes, and 6 the hub of aconventional form of it) era lly at, and comprise ragga at a relativelygreat number of these convolutlons W111 contact the ground at the sametime. i

The meeting ends of The demountablethe'band 8 may be fastened together in any 5 preferred manner asindicated at 8 in Fig. 1. The ends of the coil spring forming the tiremay be brought together at the point where the ends of the band 8 arejoined so that the convolutions of the spring may be welded to the bandas shown. The structure may then be readily mounted in position.

After the tire has been rendered a uni tary structure by the applicationof the band 8 thereto, the device may be applied to the demountable rim9. The demountable rim with the tire attached is then applied to thevehicle wheel felly in the usual manner, and after the clencher members10 have been properly attached to the wheel 1 the band engage in therecesses 12 and. hold the spring and band against circumferential orlateral movement. The unitary-structure thus provided is applied to thewheel 'felly in the same manner that the demountable rims now used areapplied. r As a relatively great number of the convolutions of thespring Tcontactthe groiind structed of a coil spring in the manner 7specified Will not only supply the desired re siliency forthe Wheel,-but Will obviate the fortire chains in Wet Weathenor necessity p s ppry' t e st preferred-embodiment of the inyention, it is Copies of thispatent 'm' ay obtained for to be understood that the invention is not;limited thereto, as various minor changes in the invention cla1m.""i

the details of eonstrliction, proportion, and arrangement of parts maybe resorted to if desired Without departing from the spirit of asdefined by the appended I claim "In adevice of the class described, anannular tire formed of a coil spring, a band Within said spring andWelded to all of the convolutions of the latter, a delnountable rim, thesaid being provided With recesses, and lugs projecting from said bandand being adapted to engage said recesses.

In testimony whereof I aflix my signa-v M 1 V. ture in'presence oftwoWitnesses. Whilethe present is a disclosure of the 1 JOHN M. JONES.Witnesses:
